[Answered] Decryption of phat PS3 HDD help?

I already know about ENCDEC keys and various encryption shenanigans on the HDD, My question is this:

Can I decrypt it without powering on my PS3?

Is there a way of pulling the AES key(s) without the help of the PS3 OS, Or maybe even bypassing the encryption altogether? I'm not sure it's possible to make the PS3 functional enough to extract the keys.

The data I'm interested in: save files and saved login info(So I only need access to the gameOS and FAT32 partitions, I think?).
